You have been told you grind your teeth at night by a partner or dentist. You are not doing it consciously — so why does it happen? The causes of sleep bruxism are varied and understanding yours matters for treatment.
Stress and Anxiety Are Major Triggers
The most common cause of nighttime teeth grinding is stress. When your mind processes worries and tension during sleep, your body responds physically. Your jaw muscles clench and grind as a physical outlet for that stress. This often increases during particularly stressful periods in your life.
Sleep Apnoea Links to Teeth Grinding
If you have sleep apnoea, you are more likely to grind your teeth. The breathing interruptions cause your body to shift during sleep, and grinding can be part of that arousal response. Many people do not realise they have sleep apnoea — loud snoring and feeling exhausted despite a full night is sleep are warning signs.
Misaligned Teeth and Bite Issues
When your upper and lower teeth do not fit together properly, your jaw muscles work harder to find a comfortable position. This imbalance can trigger grinding, especially during sleep when your brain is trying to correct the bite relationship. Orthodontic treatment or bite adjustment can help in these cases.
Medications and Substances Play a Role
Some antidepressants, amphetamines, and recreational drugs increase the likelihood of bruxism. Caffeine and alcohol also make grinding worse, particularly if consumed in the evening. Tracking your intake of these substances alongside your grinding symptoms helps identify patterns.
What Damage It Causes
Grinding wears down enamel, cracks teeth, and puts pressure on your jaw joints. You might wake up with a sore jaw, headaches, or sensitive teeth. Over time, the damage accumulates — many people do not realise how much damage has happened until their dentist points it out at a check-up.
What Helps Stop the Grinding
A custom night guard protects your teeth while you sleep. Reducing stress through relaxation techniques or counselling addresses the root cause for many people. Your dentist can fit you with a guard and help determine whether further investigation into underlying causes is needed.
